FITTING FOR STAND-PIPE SYSTEMS..

1,275,532., Original application filed March 26, 1917,

To all whom it may concern:

Be it knownthat I, WILLIAMI F. CONR kN, a citizen of the UnitedStates'of Amerlca, residing in the borough of Brooklyn of the city ofNew York, in the county of Kings and State of New York, have invented acertain new and useful Improvement in Fittings for Stand-PipeSystems, ofwhich the following is a specification. I

This application is a division of my ap-' plication filed March 26,1917, SerialNumber 157,558, the invention relating to fire extinguishingsystems employing a main Water supply line or pipe having a number ofoutlets or branches at various'points controlled by hydraulicallyoperated valves which in turn are controlled from distant points or froma common operating station by hand operated control valves; and relatingmore particularlyto a system of movable stand-pipes for buildings suchas described in Letters Patent of. the United States No. 816,152,granted to me March 27,

1906, but wherein the control pipes leading from the control valves tothe hydraulically operated valves are carried within the main watersupply pipe or movable stand-pipe, and the present invention relates tothe fitting which is placed in the pipe-line for each outlet or branch,and through whichv a control-pipe projects for connection to thehydraulically operated valve carried thereby, and which fitting alsoincludes the supportingjmeans for the control-pipes carried within thepipe-line, and the means for attaching the hand-valve for a hose-line.This fitting is herein referred to as the Y- fitting.

As described in my said application and patent, the outlets fromthewater supply or stand-pipe are controlled from an operatin station orchamber, and the Y-fitting is p aced in the pipe-line at thepoints ofoutlet. This fitting may be of any suitable shape, but I prefer to havethe body portion semi-cylindrical or U-shaped in cross-section, taperingtoward the ends and terminating in screw-threaded or flanged couplingmembers of the usual pipe sizes. The straight side of the U-shaped bodysection is openv and covered by a flat plate WlllCh is provided with acentral screw-threaded hole to receive the nipple for. the'hand-valve towhich a hose-line may be attached. [The -Y- branch may projectfromeither sideof the Specification of Letters Patent. Patented Aug. 13,1918.

U-shaped body, preferably with a long-turn,

and .with the outlet projecting at right angles to the body of thefitting or pipevide anen'largementor boss above the Y- branch, which isadaptedto be bored to a diameter larger than the control-pipe andprovided with packing material and packing rings which will allowlongitudinal movement of the control-pipe, thusforming a stuffing-box.My invention is illustrated in the accompanying drawings, inwhich'Figure l isan elevation of the fitting and showing a hydraulicallyoperated valve, hand-valve and hose-line attached thereto; Fig.2 anelevation of the fitting viewed from the right of Fig. 1; Fig. 3 avertical central section of the fitting viewed from the leftof Fig. 2,

and Fig. 4a horizontal section on the line 00-1010 of Fig. 3. I

7 Referring to'the drawings,-1 is the bod of the fitting having asemi-cylindrical or Urshape in cross-section (see Fig. 4). presenting aflat side which is covered by aplate2, secured by bolts, and thejointzbeing leaded orpacked. The diameter of the body of the fitting islarger than the stand-pipe, and tapers at both ends to pipe size-andterminating in the usual bands. As shown the ends of the fitting arescrew-threaded to re- ,7 is mounted. Thus it will be seen that thehand-valve and hydraulic-valve iareset at right angles so that in thenormal position of the stand-pipe the hand-valve-and hose will bereadilyaccessible/ One control-pipe ,8 is led out of, the fitting forconnection to the hydraulic-valve carried thereby, and as shown in Figs.3 and 4:, thefitting for this purposehas-a bossat the upper angle of thei -branch which is bored to a diameter larger than the control pipe andis provided with packing material and packing rings '9 to form astufiing-box for the control-pipe. The arrangement of control-pipesshown in Fig. 3 is that where the control station is below theY-fitting, but where the fitting is below the control station, as in acellar, the control-pipe which is to project throu h the fitting willextend downward into the tting instead of upward as shown and the pipewill have an upward bend and pass up through the stuiiing-bcx forconnection to the piston chamber of hydraulic valve 5. I prefer,however. in such case, to provide a boss 10 through which pipe 8 shownin dotted lines will pass; the boss being bored and packed as aboveexplained, and pipe 8 outsideof the fitting being provided with apetcock to drain the pipe and piston chamher when necessary. I 7

At the upper end of the fitting and abovet-he entrance of the Y-branchare two rows of lugs 11 between which are held two U- shaped perforatedplates 12, each having a large perforation (see Fig. equal to or largerthan the inside diameter of the standpipe, and a circular series ofsmall perforations. Seated between plates 12 and projecting through thesmall perforations are a series of expansion-joints for the controlpipes8. As shown, these joints are preferably in the form of cylindricalboxes having annular extensions of smaller diameter which -fit into thesmall perforations of plates 12';

the upper extensions having a packing and screw-plug forming astalling-box for the control-pipe section entering from above the joint,and the lower extension forming one member'of a union for attaching thecontrol-pipe section entering the joint from below. The union end of theexpansion-joint includes a nipple having its inner end ground conical orspherical to seat against the correspondingly ground end of the boxextension, and this nipple has a flange which is engaged by a cap andwhereby the nipple is held to its seat. The upper ends of thecontrol-pipe sections are screwed into the nipples and thus each sectionof controlpipe is supported or suspended by the union ends of theexpansion-j oints. By this means each section of control-pipe is free tocon tract or expand lengthwise without straining joints or bowing thepipes, and at the same time the expansion-joints and retaining plates 12support the control-pipes and hold them in position against the interiorof the stand-pipe and prevent lateral dis placement. v

The purpose of the large opening in the body of the fitting which isclosed by plate 2 is to permit the insertion of retaining plates 12 andexpansion-joints, and to permit making connections between those jointsand the control-pipe sections,and to permit feeding the pipe through thestufling'box and placing the packing and ring 9 in posi tion, and formaking tests, inspections and repairs.

substantially as set forth;
